Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: Avoiding the term “representation” would make the article much more consistent with a radical constructivist way of thinking. It would also open up unexpected opportunities for realizing the potential of some of its most interesting ideas, such as the connection between anticipatory drive and attention (§31).

Purpose: Constructivism postulates that the perceived reality is a complex construct formed during development. Depending on the particular school, these inner constructs take on different forms and structures and affect cognition in different ways. The purpose of this article is to address the questions of how and, even more importantly, why we form such inner constructs. Approach: This article proposes that brain development is controlled by an inherent anticipatory drive, which biases learning towards the formation of forward predictive structures and inverse goal-oriented control structures. This drive, in combination with increasingly complex environmental interactions during cognitive development, enforces the structuring of our conscious self, which is embedded in a constructed inner reality. Essentially, the following questions are addressed: Which basic mechanisms lead us to the construction of inner realities? How are these emergent inner realities structured? How is the self represented within the inner realities? And consequently, which cognitive structures constitute the media for conscious thought and selfconsciousness? Findings: Due to the anticipatory drive, representations in the brain shape themselves predominantly purposefully or intentionally. Taking a developmental, evolutionary perspective, we show how the brain is forced to develop progressively complex and abstract representations of the self embedded in the constructed inner realities. These self representations can evoke different stages of self-consciousness. Implications: The anticipatory drive shapes brain structures and cognition during the development of progressively more complex, competent, and flexible goal-oriented bodyenvironment interactions. Self-consciousness develops because increasingly abstract, individualizing self representations are necessary to realize these progressively more challenging environmental interactions.

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: In this commentary to Martin V. Butz’s target article I am especially concerned with his remarks about language (§33, §§71–79, §91) and modularity (§32, §41, §48, §81, §§94–98). In that context, I would like to bring into discussion my own work on computational models of self-monitoring (cf. Neumann 1998, 2004). In this work I explore the idea of an anticipatory drive as a substantial control device for modelling high-level complex language processes such as selfmonitoring and adaptive language use. My work is grounded in computational linguistics and, as such, uses a mathematical and computational methodology. Nevertheless, it might provide some interesting aspects and perspectives for constructivism in general, and the model proposed in Butz’s article, in particular.

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: One intriguing concept that the author introduces and uses throughout the paper is the idea of an “anticipatory drive,” which is described as explaining the systematic tendency to develop anticipatory capabilities that ultimately support goal-oriented action. Although the idea of a common mechanism that explains a multitude of capabilities can be appreciated, it is unclear if the author uses the term “drive” in a literal or metaphorical sense. Should the evolutionary advantage, the selective “pressure” for anticipatory capacities and representation be considered a drive in the sense of Hull like, for example, the sex drive, or hunger? If this is true, it should be related to some bodily control structure like the other mentioned drives. Another possibility is that the anticipatory drive is an intrinsic motivation, like curiosity, which “pushes” towards certain situations, such as those that are more predictable. If this is true, it should be explained what is the exact nature of such intrinsic motivation.

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: There are circumstances when anticipation can be maladaptive. In the following paragraphs, the occurrence of maladaptive anticipation will be illustrated in reference to psychological disorders (depression, generalised anxiety disorder, social phobia). It will be shown that anticipation does not always lead to improved control of oneself and the environment and that anticipation is not always beneficial. Finally, the question is raised of whether it is the strength of the anticipatory drive or the content of the anticipations that is the important factor in the development and construction of the self.

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: Butz proposes an anticipatory drive that is postulated to be responsible for brain function and the development of brain structure. It is especially interesting because Butz suggests that the anticipatory drive guides brain development, in addition to function. This is an ambitious and provocative proposal, and bears close examination. I focus on just one aspect here: in the spirit of constructivism, I ask, where is it?

Open peer commentary on the target article “How and Why the Brain Lays the Foundations for a Conscious Self” by Martin V. Butz. Excerpt: This paper is full of stimulating and creative ideas. It posits that an anticipatory drive is what guides the development in the brain of a set of internal motor models, specifically a set of inverse and forward models. Through these models becoming increasingly complex, a conscious self develops. This is a simple and important thesis, if true. But is it? As my title suggests, it may be so for sportsmen, with their emphasis on ever more refined motor responses. However, those of a more cerebral nature may find themselves burdened by all those coupled internal motor models and not able to think as clearly as they would like. This is not to say that prediction isn’t a useful property to possess, both for finance (especially now) and in one’s general living patterns. But the question I wish to consider is: What sort of predictive model can lead to thinking?
